Jawg Maps

Get key to access JawgLab (if you have an API key skip this)

Step 1: Signup/Login

Step 2: Getting api token

With this in place, make a GET request: https://api.jawg.io/routing/route/v1/car/#{SOURCE[:longitude]},#{SOURCE[:latitude]};#{DESTINATION[:longitude]},#{DESTINATION[:latitude]}?overview=full&access-token=#{KEY}

Note:

  • we will be sending overview as full.
  • Setting overview as full sends us complete route. Default value for overview is simplified, which is an approximate (smoothed) path of the resulting directions.
  • Jawg accepts source and destination, as semicolon seperated {:longitude,:latitude}
//using jawmaps API

//Source and Destination Coordinates..
// Dallas, TX - coordinates
$source_longitude='-96.79448';
$source_latitude='32.78165';
//Addison, TX - coordinates
$destination_longitude='-96.818';
$destination_latitude='32.95399';
$key = 'jawmaps_api_key';

$url = 'https://api.jawg.io/routing/route/v1/car/'.$source_longitude.','.$source_latitude.';'.$destination_longitude.','.$destination_latitude.'?overview=full&access-token='.$key.'';

//connection..
$jawmaps = curl_init();

curl_setopt($jawmaps, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($jawmaps, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($jawmaps, CURLOPT_URL, $url);
curl_setopt($jawmaps, CURLOPT_RETURNTRANSFER, true);

//getting response from jawmapsapi..
$response = curl_exec($jawmaps);
$err = curl_error($jawmaps);

curl_close($jawmaps);

if ($err) {
	  echo "cURL Error #:" . $err;
} else {
	  echo "200 : OK\n";
}

//extracting polyline from the JSON response..
$data_jawmaps = json_decode($response, true);

//polyline..
$polyline_jawmaps = $data_jawmaps['routes']['0']['geometry'];

Note:

We extracted the polyline for a route from Jawgmaps

We need to send this route polyline to TollGuru API to receive toll information

TollGuru API

Get key to access TollGuru polyline API

  • create a dev account to receive a free key from TollGuru https://tollguru.com/developers/get-api-key
  • suggest adding vehicleType parameter. Tolls for cars are different than trucks and therefore if vehicleType is not specified, may not receive accurate tolls. For example, tolls are generally higher for trucks than cars. If vehicleType is not specified, by default tolls are returned for 2-axle cars.
  • Similarly, departure_time is important for locations where tolls change based on time-of-the-day and can be passed through $postdata.

the last line can be changed to following

//using tollguru API..
$curl = curl_init();

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);


$postdata = array(
	"source" => "gmaps",
	"polyline" => $polyline_jawmaps
);

//json encoding source and polyline to send as postfields..
$encode_postData = json_encode($postdata);

curl_setopt_array($curl, array(
CURLOPT_URL => "https://dev.tollguru.com/v1/calc/route",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",


//sending jawmaps polyline to tollguru
CURLOPT_POSTFIELDS => $encode_postData,
CURLOPT_HTTPHEADER => array(
				      "content-type: application/json",
				      "x-api-key: tollguru_api_key"),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
	  echo "cURL Error #:" . $err;
} else {
	  echo "200 : OK\n";
}

//response from tollguru..
var_dump(json_decode($response, true));
// $data = var_dump(json_decode($response, true));
//print_r($data);

The working code can be found in main.rb file.
